fuel and air or both gaseous and fiuid fuel;

and air and feeding the same to a point. of. combustion or to a heating chamber.

The object of the invention is to produce a device of this character. having means, including series of constricted passages for feeding gaseous or fluid fuel or both to a point of combustion by pressure or suction induced by air currents traversing said constricted passages.

Another object is to produce a unitary structure of this character in which a plurality of Venturi passages are termed, whereby combustible mixture traversingsaid passages is segregated or broken into separate and ii'idcpendent streams which intersect at the point of combustion or the point of entering the heating chamber and diverge or spread at such. point.

I accomplish these objects by means of the device hereinafter more specifically described, reference being had to the accompanying drawings, forming part hereof, in which: i I

Having described my invention, what I claim and desire to secure by Letters Patont is:

l. A device for producing and utilizing; combustible mixture, which includes a shell having;' a channel therethrough, a plug or abutment secured in said shell, the side wads of said plug and the walls of said channel cooperating to form a plurality of Venturi passages, in combination with means for feeding a combustible substance into said channel at the most constricted portion o'l said Venturi passages.

2. iirlcvice for producing and utilizing combustible n'iixture, which includes a shell having a channel longitudinally thereof, the said channel being provided with means for attachment tov an air supply pipe, a plug; obstructing said channel, the walls of said plug and the walls of said channel co-operating to form dual Venturi passages, the

said plug having a centrally disposed chamberand a plurality ofminute open ngs extending from said chamber towards the walls or" said channel, and means to supply said chamber with a combustible substance.
